  • Low cost for control achieved
  • High torque at startup and low speeds
  • Ruggedness
  • Simplicity of construction
  • Can operate in an open loop control system
  • Low maintenance
  • Less likely to stall or slip
  • Will work in any environment
  • Can be used in robotics in a wide scale.
  • High reliability
  • The rotation angle of the motor is proportional to the input pulse.
  • The motor has full torque at standstill (if the windings are energized)
  • Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3–5% of a step and this error is non-cumulative from one step to the next.
  • Excellent response to starting/stopping/reversing.
  • Very reliable since there are no contact brushes in the motor. Therefore, the life of the motor is simply dependent on the life of the bearing.
  • The motors response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
  • It is possible to achieve very low-speed synchronous rotation with a load that is directly coupled to the shaft.
  • A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.



Q1: What about your warranty?
A: We guarantee is one year . for sea order . is 15months.
Q2: Do you have any certificates?
A: Yes, we have. All the motors have been approved by CE and Rohs.

A: Yes. We can supply OEM andmake customized design for any specific application.
Q4: How can be your brand distributor?
A: We will check your capacity and help you promote and expand the market.
Q5: What's the delivery time ?
A: Except special order. For samples usually 7-15 working days . for batch order . usually 20-25days.



7.Stepper Motor Applications

  • As the stepper motor are digitally controlled using an input pulse, they are suitable for use with computer controlled systems.
  • They are used in numeric control of machine tools.
  • Used in tape drives, floppy disc drives, printers and electric watches.
  • The stepper motor also use in X-Y plotter and robotics.
  • It has wide application in textile industries and integrated circuit fabrications.
  • The other applications of the Stepper Motor are in spacecrafts launched for scientific explorations of the planets etc.
  • These motors also find a variety of commercial, medical and military applications and also used in the production of science fiction movies.
  • Stepper motors of microwatts are used in the wrist watches.
  • In the machine tool, the stepper motors with ratings of several tens of kilowatts is used.
